What Miami Homeowners Say About Mercer Roofing Co Miami
A review page only matters if the words on it sound like the person who actually wrote them. That’s what you’ll find here. We ask every Miami homeowner we work with to tell us the truth about the job, the crew, the price, and what happened after we left. The reviews below are not curated for five-star polish. They’re just what people told us after living with their roof through a Miami summer. We earn each one the same way: a written price before anything starts, a background-checked technician who badges in at the door, and a 365-Day Done Right Promise in writing on every repair. If it’s not right within a year, Mercer makes it right.

“We had water staining across the ceiling in our dining room and two other companies told us we needed a full replacement. Mercer sent a tech who found the real problem: a rusted-out flashing detail where the roof meets the chimney chase. He replaced the flashing, resealed the decking around it, and the stain dried out within a week. Total cost was under $600. That was eight months ago, and not a drop since.”

“The crew showed up in clean uniforms and the lead tech handed me his photo ID before he even stepped inside. I’d already seen his name and picture in the text they sent the night before. He walked the roof with me on a tablet, showed me exactly where the shingles had lifted along the ridge line, and wrote the price down before touching anything. The number on the invoice matched the number on the quote to the penny.”

“A limb off our mango tree tore through the underlayment during a September storm and we had water coming into the guest bedroom. Mercer answered the phone at 9:40 at night, no voicemail. They had someone out the next morning who tarped the damaged section, then came back with a full repair quote in writing. New decking, new underlayment, new shingles matched to our existing GAF color. The patch blends so well you can’t find it from the street.”
Lisa R. – The Roads, Miami
“I called on a Tuesday because I’d lost a few shingles in a wind gust off Biscayne Bay. They told me over the phone what a repair like that typically runs in Miami before I even scheduled anything. The tech showed up on time, badge clipped to his shirt, and walked me through what he found: the shingles were there, but the nails underneath had backed out. He reseated everything, replaced the broken ones, and left me a written guarantee for the work. No upsell, no pressure.”
Paige S. – Coconut Grove, Miami
“We had a full tear-off and new CertainTeed shingle install done in July. I was worried about the afternoon storms slowing things down, but the crew staged the job in sections and kept the decking covered with underlayment between shifts. Grant Whitlock himself came out on day one to walk the property and confirm the flashing plan around our skylights. The written quote he gave us before the job started held, even when they found three sheets of rotted decking that had to be replaced. That extra work was priced out and added to the line item same day, no mystery charges.”
Stephanie R. – Shenandoah, Miami
“The roofer who came out for our leak check was the same person whose photo I’d been texted, wearing the same uniform in the picture. He found a cracked tile along our barrel tile roof where the solar mounts had been installed years ago. He explained the repair in plain English, gave me a written price before he got his tools off the truck, and had it fixed and sealed that visit. He also took photos of everything he did on the roof and texted them to me before he left. I’ve never had a contractor do that.”
Norma R. – Little Havana, Miami
“Our flat roof over the carport had been patched by three different companies in the past ten years. Every spring we’d get a small leak in the same corner. Mercer’s estimator spent almost an hour up there and came down explaining that the previous patches were all layered on top of failed flashing where the flat roof met the stucco wall. They cut it back, installed new metal flashing, and laid a proper modified bitumen patch with a primer underneath. The repair came with a 365-day guarantee in writing, and I actually used it once six months later when a seam opened slightly after a heavy rain. They came back at no charge, same tech, and fixed it properly. That’s what a guarantee should be.”
Lisa R. – Coral Gables, Miami
“I’m a property manager with seven rental units across Miami, so I’ve dealt with a lot of roofers. The thing that stood out about Mercer is that the tech who handles the estimate is the same person doing the repair. He’s background-checked, ID-verified, and arrives looking like he respects the fact that he’s walking through someone’s home. We’ve used them for three separate repairs this year, all on different properties, and every single one came with a written price first and a written guarantee on the work. Our tenants get the same badge-at-the-door treatment every time.”

They mention a technician who showed a photo ID at the door and whose name they had already seen on their phone. They mention a repair that failed and got fixed again for free under the 365-Day Done Right Promise. That’s not an accident. It’s the Threshold Standard, the operation framework every Mercer Roofing Co Miami technician works under. Each technician is background-checked, identity-verified, uniformed, and badged.
